'JOHN DANIEL MONAGHAN, OF VINCENT, IOWA.

SLIDE FOR TONGUELESS CULTIVATORS.'

SPECIFICATION formingpart of Letters Patent No. 533,962, dated February12, 1895.

Application filed October 4, 1894.

To all whom it may concern:

-Be it known that I, J OHN'DANIEL MONA GHAN, a citizen of the UnitedStates, residing at Vincent, in the county of vVifebster and State ofIowa, have invented certain new and usefulImprovem ents in Slides forTongueless Cultivators; and I -do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to, theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain new and useful improvements incultivator-s and more especially to the class of tongueless cultivatorshaving axles hinged so that the vertical side portions of the elevatedportion of the axle may be oscillated independently in vertical planes.

My design is to improve upon the construction of the draft plates andthe adjustable runner or shoe as shown in the well known Patteecultivator, Patent No. 195,042, of September 11, 1877, by whichimprovement the runners which are held in slots of the draft plate areretained by a spring actuated bolt, thus dispensing with the use of awrench for unloosening the nut, it merely being necessary in myinvention to press in on a burr at the outer end of the spring, and thebolt maybe readily released and slid along the slot to the other end ifdesired.

To these ends and to such'others as the invention may relate, the sameconsists further in the novel construction, combination and adaptationof the parts as will be hereinafter more fully described and thenspecifically defined in the appended claim.

' I clearly illustrate myinvention in the accompanying drawings, whichwith the letters of reference marked thereon form a part of thisspecification, andin which drawings Figure 1 is a perspective view ofthe draft plate as attached to a cultivator and carrying in its slot-theground shoe. Fig. 2, is an ensenn No, 525,046. (No model.)

larged detail view of the draft plate and shoe; Fig. 3, a sectional Viewthrough the spring actuated bolt, shoe and draft bar.

,7 Reference now being had to the details of the drawings by letter, Adesignates the plow beams; B, the axle; O, a draft bar or plate, whichis hinged in any suitable way, to the part 0' of the axle, and theforward end formed into a hook D to which it is designed to attach thesingletree.

E is a brace from the axle to the draft plate and is slotted to permitthe draft plate to os cillate.

F is a runner or shoe, its upper end adj ustably held in the slot 0 bythe spring actuated bolt G, which is provided with an elongatedflattened head G, with' ears g, which head is designed to be held in arecess H, by means of the springK interposed between the washer L, andthe burr or cap L which screws on to the threaded end of the bolt G. Asimilar shaped recess is provided at each endpf the longitudinal slot 0,whereby, when it is desired to change the shoe, which is held at one endof the slot 0, to the recess at the extreme end thereof, by simplypressing upon the burr L the head of the bolt will be released from therecess H in which it is seated,

and will be in the position, seen in dotted lines G, and maybe readilyslid along the slot 0, and when the head of the bolt comes to the recessat the extreme end of the longitudinal slot, the head of the bolt, underthe tension of the spring K, will drop or lower into the said recess,thus changing the angle of the draw bar or plate 0. By this arrangementof the spring actuated bolt, in which resides the gist .of my invention,it will bereadily seen that the necessity of having a wrench, will bedispensed with, and that the change of the shoe from one recess H to asimilarly shaped one at the extreme end of the slot 0, may be readilyand quickly accomplished.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is

In a draft plate and sliding shoe, for a Washer all substantially asshown and de [0 tongueless cultivator, the combination of the scribed.

draft plate 0, slotted as described and pro- In testimony whereof Iaffix my signature vided with the transverse recesses at each inpresence of two witnesses.
